TORSUS intrusion system line is employed for the protection of rigid metal fences such as heavy welded panels and palisades.

TORSUS consists of special torsion sensors which perceive the flexions and the torsions of the bearing posts during an intrusion attempt for breaking through and climbing. The particular shape of the sensor and the use of a special piezoceramic transducer provide TORSUS systems a very high sensitivity which can even detect climbing actions performed without causing shocks, vibrations or noises.

TORSUS systems can be installed on different types of grill fences, both industrial and craftmade. The sensors are fixed to the base of the bearing posts, along the inside fence; in some cases, they can be even installed inside the posts, becoming completely invisible.

All TORSUS systems and their signals can be centralized over DEA NET to be integrated into DEA MAP software or 3rd party devices and software, also with IP protocol.


Climbing detection.

TORSUS systems not only discriminate and detect breach, breakthrough and climbing events, but also climbing perfomed without causing vibrations and noises.

Immunity to environmental disturbances.

TORSUS systems have a very high tolerance to adverse climatic events such as rain, snow and extreme temperatures, and to man-made factors such as roads, motorways and railways.

Compatible with the vegetation.

TORSUS detectors are compatible with high grass and bushes and can be even installed on fences completely covered with evergreen climbing plants.

24h protection.

Working on the boundary of an estate, TORSUS systems offer a round-the-clock protection letting people move freely inside the perimeter.

Prewired sensor-strings.

All TORSUS detectors are wired, sealed and tested at the factory to avoid on site possible wiring mistakes and to guarantee the tightness of all the junctions from dust, water and humidity.

Maximum laying flexibility.

The sensor-strings adapt themselves to the terrain conformation and to the direction of the perimeter, making it possible to follow bends and differences in level, avoid obstacles and overcome possible discontinuities along the fence.
TORSUS line is composed of two systems:
Sensori TORSUS lungo ferrovia


Fence-mounted system suited for any kind of perimeter in terms of complexity and dimensions.
Sensori TORSUS su recinzione residenziale


Stand-alone version of TORSUS 50 system provided in ready-to-install kits.



TORSUS 50 is a perimeter intrusion detection system for rigid metal fences. It deploys passive sensors provided in prewired strings up to 50 metres long. TORSUS 50 is suitable for the protection of perimeters of any size and complexity, both in residential and in industrial sector.

Different versions available.

TORSUS 50 is available in three colours – grey, green and black – and in strings of different distance between the sensors (2, or 2,5 metres). The system can be also provided with polyamide sensors (highly resistant to chemical agents) or with cable protected with flexible metal sheath.

50-metre alarm zones.

TORSUS 50 is available in sensor-strings of 50-metre length maximum, to provide an accurate identification of the section under alarm and to be easily coupled with the videosurveillance systems (CCTV).
Lunghissima vita d'esercizio

High wear resistance.

Specially designed for external use, TORSUS 50 sensors and cables have a very high resistance to UV rays and to temperatures varying from -40° to +80° C. The piezodynamic transducer of the sensor is virtually inexhaustible and is immune to electrical failure.

10-year warranty on the sensors.

We are so confident of the robustness and quality of our detectors that we grant a 10-year warranty* on them.

 * Warranty period valid in European Union only.



TORSUS COMPACT 50 is a stand-alone version of TORSUS 50 system and is supplied in a ready-to-install kit for the protection of a 50-metre perimeter. It is particularly suitable for the protection of small residential and commercial sites.
Semplice ma performante

Simple yet sophisticated.

TORSUS COMPACT 50 uses TORSUS 50 technology and sensors, therefore provides the same level of reliability and performance. It differs from the latter for its simplified range of versions, for its “all inclusive” packaging and for being more suitable to protect small perimeters, especially in residential areas.
Fornito in kit

Ready to install.

The system is supplied in a kit (Module) including a prewired sensor-string, a small pre-assembled electrical cabinet (Analysis Unit) and a set of accessories to install and start-up the system in a very quick way.


The 50-metre standard coverage can be expanded for further 50 metres for a total length of 100 metres, using a special expansion module which will be installed inside the pre-existing control unit.
Sensori indirizzati

Ideal for small compounds.

The COMPACT version of TORSUS 50 system has been especially designed for compounds of maximum 100-metre length, where it provides very good ratio between price and performance.
